Titel:

820-3662 PPDCIN_G3H and PPBUS_G3H short to ground

Original-Beitrag von::

Hi, I have a macbook pro 2013 with a short to ground on PPDCIN_G3H and other rails it share (PPDCIN_G3H_INRUSH, CHGR_PHASE etc.) [br]

I tried to replace ISL6259, but no change. Then I tried to inject voltage to PPDCIN_G3H_CHRG. It draws 3 A at 0.2 V and Q7130 is slightly warm, but when I inject voltage on the other side - CHGR_PHASE, nothing gets really hot.  So I guess the problem is on that side of FET. Fuses F7140 and F7141 are good, so PPBUS_G3H is also shorted[br]

Any ideas what i should do? Thanks
